Hello All,
I have a DP570 that goes blank after startup. When the unit was new out of the box the "Danfoss" logo would appear just like any brand new unit. As soon as I installed my program it goes blank after startup. The little clock appears, but then goes blank.
I developed this program on a prototype machine with a DP570 with a camera input and had no problems like this. After prototyping we decided we didn't need a camera input so production units do have it. I changed the hardware API within my program accordingly, but now I have this problem. I must have done something wrong in this process. Any ideas what I did wrong? Your help is appreciated.
Thanks.

What about back light? Is it more than 30%, 50%?

Hi
Yes, that could be it. Maybe you had a NV parameter for the backlight and had it set to a value on your old device. Now when you have the new device the value is by default 0 for that NV until you change it.
If you don't find a solution, please send your application to plus+1helpdesk@danfoss.com, then we could have a look.
Best Regards

I had an issue like this with a DP570 quite a while back, and it was an issue related to ambient temperature. Danfoss revised the .hwd file to fix it. Is the .hwd template you used over a couple of years old, and is ambient temperature down around freezing?

Thanks for all the replies and ideas!
It was the backlight. I discovered an error in my logic when setting the default parameter for the backlight, so after an initial install the parameter was set to zero. I have fixed my error and now the correct default parameter gets set.
Thanks again for your help!
